Katsaridaphobics beware!

A rather large wood roach of the genus Parcoblatta (I presume) investigates the surface of a leaf. John Howard and I were out late into the night last Saturday in Adams County, searching for nocturnal critters. We saw several of these roaches, which are common in southern Ohio woodlands. While they are in the same order (Blattodea) as the loathed pest cockroaches that infest dwellings, these are native roaches that live in natural habitats.

Nonetheless, if you are a sufferer of katsaridaphobia - fear of cockroaches - you're not going to like these things, harmless as they may be. The cockroaches don't care whether you like them or not. After all, Homo sapiens is just a short-term blip on the evolutionary time scale. From a cockroach's perspective, we have yet to prove ourselves. After all, humans in roughly our modern form and as described as H. sapiens only arose about 200,000 years ago. The cockroaches have been at the game of life for FAR longer than that. Fossilized ancestral roaches date back some 300 MILLION years, and more or less modern blattopterans have been around for some 145 million years. Cockroaches are successful, no doubt about it.

If, in addition to the aforementioned katsaridaphobia, you are also afflicted with arachnophobia, you're really not going to like this photo. John and I, however, were delighted to stumble upon this scene. A very large nursery web spider, Pisaurina mira, has captured a wood roach and is eating it. This is a scene that has played out for hundreds of millions of years, in one form or another. Spiders have an even more ancient history than do the roaches, having arisen some 400 million years ago. And as we can see from this photo, the spiders are most likely to dominate when it comes to roaches.

While more than a few people are turned off, often to a great degree, by spiders and roaches, you can't argue with success. These orders of animals have been around longer than many minds can comprehend, and they'll surely be on mothership earth long after Homo sapiens has departed.

If you've made it this far, I offer an antidote to the horrorshows above: a "cute" Northern Saw-whet Owl. Even though the owl is every bit the formidable hunter that the spider is, far more people like them.

Thanks to Dr. Rich Bradley for confirming the identity of the nursery web spider.

We had those big wood roaches in TX, too, and I have many less than fond memories of them. Every once in awhile, they'd get into the house....eeeeyuck!!

I notice that spider likes wings. I prefer mine BBQ'ed...

The Pinching Beetle, a rather brutish looking bug

The world is awash in beetles, and they come in all shapes and sizes. Few of them can match the intimidation factor of a Pinching Beetle, Lucanus capreolus, though. Those formidable looking mandibles look like they could slice off a finger.

Today was one of those coolly diverse days. I started off down in Fayette County, visiting the farm of a friend. He has restored about 25 acres of wetlands, and the response by the animal community has been nothing short of phenomenal. Blizzards of dragonflies of many species, amphibians galore, and nesting Blue-winged Teal, Pied-billed Grebe, and Sora. Among MANY other things. And all in a short two years. Add water and they will come.

Then, working my way home, I ducked into a Madison County cemetery that has a thriving population of Thirteen-lined Ground Squirrels, and shot images of our native prairie dog. Then, I stopped at a spot along Little Darby Creek, waded on in, and procured some pretty nice shots of various stream bluets and dancers. …

Calliope Hummingbird in central Ohio!

A hatch-year male Calliope Hummingbird strikes a pose. Small but tough, the hummingbird was feeding actively yesterday in 39 F temperatures. It frequents feeders and gardens at a home in Delaware County, Ohio, about a half-hour north of Columbus.

Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isn't surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allen's, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default "vagrant" hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allen's Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi…

Snowy owl photography tactics - and things NOT to do

A gorgeous juvenile female snowy owl briefly catches your narrator with its piercing gaze. It's doing its Linda Blair/Exorcist trick - twisting its head 180 degrees to look straight behind. Owls have 14 neck vertebrae - double our number - which allows them such flexibility.

These visitors from the high arctic have irrupted big time into Ohio and adjacent regions, with new birds coming to light nearly every day. Probably 80 or so have thus far been reported in the state, and some of them have stuck around favored spots and become local celebrities.

I went to visit one of these birds this morning - the animal above, which was found last Friday by Doug Overacker and Julie Karlson at C.J. Brown Reservoir near Springfield. In the four days since its discovery, many people have visited as is nearly always the case when one of these white wonders appears near a large population center or is otherwise very accessible.

And as is always the case, people want to photograph the owls. And th…
